SYMPTOM
PROBLEM
The sound level on one of my
Addam's mysteriously -and
very intermittently- opens
wide and blasts everyone in
the location and settles back
down in time for me to walk in
and see nothing wrong.
The game is displaying English text, but the audio is in Japanese.
~e checked connections on
-ribbon cables, coin door
switches, etc. Apparently not a
connector problem.
SOLUTION
Note that the English setting only affects the screen text. The
voices will remain the same. Some locations will complain about
their game, that is supposed to be set for "English", if they are not
aware of this quirk.

SOLUTION
Try replacing the solid state
pot it has been trouble on more
than a few sound boards.

WELLS GARDNER
K7000
No HIGH VOLTAGE

SYMPTOMS
Wells Gardner K7000 series. No high voltage. B positive too high:
140 to 160 Vdc. High voltage shut down.
SOLUTION
Note: All checks done with no power to monitor.
• Check fuse Fl
If Fl is open, replace it -but don't apply power to monitor yet.
• Check Qll horizontal output transistor for short.
Place your digital meter to Diode Check mode. With the positi
(+) lead of your meter to ground and negative (-) lead to the
collector of Qll. The collector of Qll is the tab mounted on the
heat sink. If Qll shows shorted before you pull it out, check
capacitor C36 for short. If shorted, replace it with Wells Garner
part #046x0551-003.
• After you replace C36, recheck for shorted condition of Q 11. If
it's okay, then ...
• Check the voltage regulator (IC4) between pins 1 and 4-should
read on your meter about .184 with the positive lead on pin 1 and
negative lead on pin 4. If shorted replace it.
MONITOR AT THIS POINT SHOULD START UP.

• With monitor running, check B positive IC4 pin 4 -should be
between 123 V de and 130 V de.
• If monitor runs, then shuts down after about 5 minutes -replace
D18 damper diode even if it checks okay.
This should solve most all your high voltage problems on th~
monitor.
